The most re-tweeted photo ever was Ellen DeGeneres's star-studded Oscar selfie. OK. So Colin Powell is not a big tweeter, but yesterday the former secretary of State posted on his Facebook page a photo of his very handsome young self, looking in the mirror with camera in hand. Black-and-white, pretty old-fashioned, but it allowed Powell to boast: I was doing selfies 60 years before you Facebook folks.
